Understanding How We Understand Throwing like a Girl

I caught this intriguing piece last month on gender/sex differences in throwing. The article is framed, sadly, as a "nature vs. nurture" debate. It reports on both bio-kinetical explanations (actually quite speculative) and cultural comparative research. Here is the graphic that helps tell the story:

The competing explanations could work well in a classroom discussion on their own, but an analysis of the author's framing of the explanations would work even better. It's not just that there are divergent explanations for gendered outcomes; what's really interesting is that we talk about those divergences in illuminating ways.
